Do you know if you still have to be a member (ie pay monthly subs) to use the gym?
I'm not talking about the one in the hotel, but the little one in the Social Centre.
I was there last week. The doors were open but I couldn't see an attendant and there wasn't any signs to say you cannot use it unless you join.
From memory, what Polaris were asking last year for monthly membership fees was quite expensive (think it was between 45 to 60 euros a month) and I would guess there weren't many takers, so now it is free for all.
